What is plan to support design time features from DataGrid.

I'm a third partner control provider, I'm researching to write a control like DataGrid. I found that it is not good for training of a newbie. he cannot understand how to use it without MSDN. WinForm's DataGridView is good from this view point.

I think some design time feature is necessary, like Smart Tag.

What is plan your team? maybe give us some information can help us to do better from compatibility view of user experience with your DataGrid.
